From the perspective of the author Hemad, what is the significance of writing and reading about Sai Baba's life, as mentioned in Chapter 43?

In Chapter 43, the author Hemad reveals his profound personal motivation for writing the Satcharitra. He states that the 'remembrance of the glory of God's devotees, their bhajan, or kirtan' is the most effective means to purify the inner self and wash away accumulated sins. Hemad views himself as merely an instrument, stating that Sai, the 'Almighty', creates the 'wonderful love' and devotion within him. He believes Sai himself increases the greatness of the life story. For Hemad, as expressed in Chapter 43, chronicling Sai's life is an act of supreme devotion that glorifies the path of 'bhajan' (devotional singing) and helps devotees transcend worldly existence.
